Recently, the rapid advancement of the IT industry has resulted in
significant changes in audio-system configurations; particularly, the
audio over internet protocol (AoIP) network-based audio-transmission
technology has received favourable evaluations in this field. Applying
the AoIP in a certain section of the multiple-cable zone is advantageous
because the installation cost is lower than that for the existing
systems, and the original sound is transmitted without any distortion.
The existing AoIP-based technology, however, cannot control the
audio-signal characteristics of every device and can only transmit
multiple audio signals through a network. In this paper, the proposed
Audio Network & Control Hierarchy Over peer-to-peer (Anchor) system
enables all audio equipment to send and receive signals via a data
network, and the receiving device can mix the signals of different IPs.
Accordingly, it was possible to improve the system-application
flexibility by simplifying the audio-system configuration. The research
results confirmed that the received audio signals from different IPs
were received, mixed, and output without errors. It is expected that
Anchor will become a standard for audio-network protocols.
